North Mercer Island/Enatai sewer upgrade

Project update

February 6, 2019

The City of Mercer Island has postponed their Community Open House until February 28 due to inclement weather. King County team members will be there to discuss the sewer upgrade and how King County will coordinate with the City of Mercer Island’s Aubrey Davis Master Planning process. We hope to see you there!

If you or someone in your community would like to learn more about the project, please contact Kristine Cramer, Kristine.cramer@kingcounty.gov or 206-477-5415 to schedule a briefing.

Project description

With over 400 miles of pipes moving wastewater to one of our award-winning treatment plants, King County WTD works hard to maintain our system. We inspect and monitor our regional system and update plans for needed upgrades.
